Supersuck seasonal overview
Supersuck sits in the heart of the Indonesian archipelago, exposed to a year-round Southern Ocean groundswell train. Although the beach faces northwest, the wave records tell a clear story: the reliable swell window is SSW-SW, while the N-NW window remains largely dormant in this dataset. The quality of the surf is governed by the monsoon cycle - when the northwest monsoon blows, onshore winds trash good waves; when the southeast trades take hold, offshore ESE-SE winds unlock the full potential of the south-tracking groundswell.
Best Surf Season (April - October)
From April through October, the southeast monsoon becomes the dominant wind regime. Offshore ESE-SE flow pushes ideal-conditions percentages into the 70s and 80s, while Southern Ocean groundswell averages 1.3-1.7m (4-6ft) with periods of 13.8-14.4s. May, September and October are the standout quality months; July and August deliver the biggest, most powerful swells but with stronger trades and a bumpier surface.
Fair Surf Season (March and November)
March and November are transition months. March sees the first clean ESE-SE windows (41% ideal) and long-period 13.4s SSW swell as the wet season fades. November still holds 78% ideal winds and 1.3m (4-5ft) / 13.2s SSW groundswell, but the monsoon is beginning to stir. Both months offer plenty of rideable waves if you can pick the windows.
Low Surf Season (December - February)
The northwest monsoon is in full swing from December through February. W-WNW-NW-NNW onshore winds dominate, ideal wind drops to 15-34%, and precipitation averages 7.6-8.6mm/day. The swell is still 1.3m (4-5ft) with 12.6-12.8s period, but persistent rain and cross/onshore winds make for messy, low-percentage surf. Only committed locals and flexible travelers need apply.
